METAL CEILING..

SPECIFICATION forming part of Letters Patent No. 434,353, dated August12, 1890.

Application filed November 5 l889. Serial No. 329,312; (No model.)

To all whom it may concern:

Be it known that I, HENRY S. NORTHROP, of New York city, in the countyand State of New York, have invented a new and Improved Metal Ceiling,of which the following isa full, clear, and exact description.

My invention relates to that class of metal ceilings in which the metalis applied to the ceiling in thin stamped sheets or plates and attachedto the same by brads, nails, or screws. It is usual in making theceilingplates to provide them with a raised bead for the purpose ofstrengthening the sheets near the edge, and with a projecting flange of,say, one-fourth of an inch around the outside of the bead. They areattached to the ceiling by nails driven through the flanges, the flangeon one plate overlapping that on the other. This brings the raised beadson the various plates close together and makes the joints and nail-headsbetween the plates very noticeable. The object of my invention is toremedy this defect and give to the ceiling the appearance of a singleembossed sheet.

To this end my invention consists in the construction and arrangement ofparts hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the views.

Figure 1 is a broken plan view of two plates of my invention attached toa ceiling; Fig. 2, a cross-section of the same on the line 2 2 of Fig.1; Fig. 3, a plan view showing another style of ornamentation, and Fig.4 a cross-section of the same on the line at 4 of Fig. 3.

The views show different styles of ornamentation and the figures inrelief on the flanges of the plates should harmonize with the design onthe main plates, so as to aid in giving to the entire ceiling theappearance of a single embossed plate.

The plates A are of the usual construction with the exception of theflanges, as described below. The plates have the usual bead B near theedge and extending entirely around them, said beads serving tostrengthen the sheets and to assist in making an even joint. The plateshave flat flanges a, which project beyond the beads, and on the flangesis ornamentation in relief, such as the separated bosses at and a Anystyle of ornamentation may be used, the style conforming preferably tothe style of ornamentation on the main plate. the flanges of but twosides of the plate, as the other two flanges will be overlapped by theflanges on the adjoining plates. The plates are attached by nails driventhrough the plates and through the flanges. The plates are applied insuch a manner that the ornamented flanges will overlap the plainflanges, and the nails are driven between the bosses a a so that theywill not be prominently displayed, and as the ornamentation on theflanges conforms to the ornamentation on the main plates the jointsbetween the plates will not be noticeable. I

Having thus described my invention, I claim as new and desire to secureby Letters Patent In a metal ceiling, the combination of-two adjoiningplates having parallel beads near their outer edges and flangesprojecting beyond the beads, one of said flanges overlapping the otherand having ornamentation in relief thereon, said ornamentations beingseparated from each other to afford spaces for the attaching-nails,substantially as described.
